FREDERICK A. STEVENS, OF PROVIDENCE, RHODE ISLAND, ASSIGNOR TO STEVENS AN CQMPANY, INCORPORATED, A CORPORATION OF RHODE ISLAND.

FRAME FOR EYEGLASSES AND STEEC'IACLIES.

To all whom it may concern:

Be it known that I, FREDERICK A. S:rn VENS, a citizen of the United States, res dmg at Providence, in the county'of Providence and State of Rhode Island, have invented certaininew and useful Improvements in ually required lenses into the frame identitied as adapted to accommodate a. lens ofsuch a size, It usually happens, however,

that the rims of the frame when ready for use have interior dimensions materially different from the dimensions originally indicated therefor. This is due to changes of temperature. bending, and I other circumstances: and when the rims are of celluloid, which is the most usual material for rims at the present time; the warping and shrinking of these rims are excessive.

The essential objects of my invention are to form a. support or brace for the rim of a f 'amc against collapse, warping. or shrinking; to combine in. such a means means for indicating the dimensions, and identify the axial line of the rim: to avoid the use of tags; to.provide a bracing means which will permit by means of the frame itself a test for required facial dimensions; and to attain these ends by a device simple to construct, inexpensive to manufacture, durable in character, and adapted to facile insertion and removal, and which. shall not easily be 'lost.

To the above ends essentially my invention consists in such parts and combinations of parts as fall within the scope. of the appended claims. 2

In he accompanying drawings which form a part of this specificatiom- Figure 1 is afront elevation of a pair of spectacles embodying my invention,

Specification of Letters Patent. 4 Patented Aug, 14;, 1917,

Application filed February 21, 1917. Serial No. 150,033.

Fig. 4, a similar view ofreduced dimensions of a modified form of the same.

Like reference characters indicate like parts throughout the views. i

In thepresent instance, my invention is illustrated as embodied in a spectacle frame comprising the bridge 6 attached to rims 8 which, in this instance, are of celluloid; the

rims being split as usual andprovided with is convenient if and when the frames are being used to test theeyes for pnpilary distances. Similar oppositely disposed marks 19 may be accompanied 'by measurement inscriptions 20 indicating, for. instance, the measurement in millimeters. of the lens adapted to the rim.

Each brace is seated in a groove 13, and when the lens is ready to be inserted into the groove 13. the brace isremoved. If and when the brace isofh metal with sufilcient resiliency, the brace may be manually sprung into andjo'ut of its seat. When the material is rigid, it is found more convenient for these purposes to loosen the screw 10, and separate the split end of the rim.

It will be observed that the snug engagement of the brace aloug'its entire periphcry with the inner face of the rim insures against any warping or bending of the latter and that theface of the brace afiords an area adapted for receiving n rkings of dimensions that are permanent in character and not liable to be lost or confused. Further, it will be seen that the brace, before it is discarded for the lens, may be employed for visual examination because of the great area of its opening, and this purpose is rendered more complete when the axial marks llli are, present.

The braces 17 may 1111? an outline other than circular .to accommodate a non-circu rim. If for instance, the rim is oblon or elliptica the ring 23 may be of similar orm such as shown in Fig. 4.

I claim 1. In eyeglasses or spectacles, the combination with the rims, of removable open braces frictionully. engaging the interior of the rims. v V I 2. In eyegliisses or spectacles, the combination of rims provided with internal seats, and removable open braces mounted the seats.

3. In eyeglasses or spectacles, the combi-' nation of rims, and annular metallic braces mounted in the rims and bOdllY removable to allow of lenses being inserted in their stead.

4. In eyeglasses or spectacles, celluloid rims or the like, and rigid parts removably retained therein.

5. In' eyeglasses or spectacles, oelluloid rims'or the like, and rigid metal parts removably retained therein to brace the same and prevent warping. I

In testimony whereof I have afiixed my signature in presence of two witnesses.
